A clear positive relationship is also evident between morbidity and difference between model-estimated and actual number of packs transfused.
However, even after adjusting for age, gender, patient's place of residence and co-morbidity, the difference between the public practices model and the other was still 19 28% (Table 5).
A drawback of this study is that we could not differentiate between actual morbidity differences and artefacts of the recording system.
Globally, the morbidity profile-related difference between the participants and non-participants was not significant.
An intermediate value (49.5%) was recorded in group I. Figure 2 shows percentage morbidity against the difference between the actually transfused and model-estimated number of PRBC.
However, comparing the individual categories of severe morbidities, the differences between misoprostol users and non-users were not statistically significant (all p-values > 0.05).
While potentially curative treatments exist, they are associated with substantial morbidity and the five-fold difference between prostate cancer incidence and mortality in many developed countries indicates that there is substantial over treatment of indolent neoplasms (Etzioni et al, 2002).
Three of the 5 studies that reported on neonatal morbidity found no differences between the control and treatment groups or dose-dependent effects of iron supplementation on the overall incidence of morbidity [ 31, 34, 35].
Where there was no co-morbidity, there was no significant difference between black and white groups (OR 0.789, 95% CI 0.432 - 1.441; I2 = 76.081).
Gaylin and Kates determined the importance of morbidity and mortality differences between population subgroups, using the HIV/AIDS pandemic as a case study, and showed important inconsistencies with the optimistic, equitable trends implied by ET theory, suggesting that the modern picture may be more complex than the original theory could predict (21).
